摘要
针对故障引起的跌落的补偿问题,利用有效值算法,采用统计学原理有效区分电压跌落的原因,即由系统故障、变压器饱和或电容器投切造成的。对于后两者引起的跌落属于系统中的正常现象,无须启动补偿设备,避免了不必要的设备损耗和资源浪费。
Aiming at compensation in time with fault events, this paper adopted a novel statistical-based detection method to distinguish reasons of voltage sags, which caused by system faults, transformer saturation events or capacitor-switching events. Voltage sags belong to two events afterwards are nomal in systems, and needn＇t switch on compensation device, averted unnecessarily loss of device and resources waste.
